This page will tak about how to make QUEUE TREE in RouterOS that with Masquerading for more than two interfaces. It’s for sharing internet connection among users on each interfacess. In manual this possibility isn’t writted.

First, let’s set the basic setting first. I’m using a machine with 3 or more network interfaces:

[admin@instaler] > in pr

# NAME TYPE RX-RATE TX-RATE MTU

0 R public ether 0 0 1500

1 R wifi1 wlan 0 0 1500

2 R wifi2 wlan 0 0 1500

3 R wifi3 wlan 0 0 1500

And this is the IP Addresses for each interface:

[admin@instaler] > ip ad pr

Flags: X – disabled, I – invalid, D – dynamic

# ADDRESS NETWORK BROADCAST INTERFACE

0 10.20.1.0/24 10.20.1.0 10.20.1.255 public

1 10.10.2.0/24 10.10.2.0 10.10.2.255 wifi1

2 10.10.3.0/24 10.10.3.0 10.10.3.255 wifi2

3 10.10.4.0/24 10.10.4.0 10.10.4.255 wifi3

On the public you can add NAT or proxy if you want.

Mangle Setup

And now is the most important part in this case.

We need to mark our users. One connectoin for upload and second for download. In this example I add mangle for one user. At the end I add mangle for local transmission because I don’t QoS local trafic emong users. But for user I need to separate upload and download.

And now, the queue tree setting. We need one rule for downlink and one rule for uplink. Be careful when choosing the parent. for downlink traffic, we use parent “global-out”, because we have two or more downloading interfaces. And for uplink, we are using parent “public”, we want QoS uplink traffic. (I’m using pcq-up and download from manual) This example is for 2Mb/1Mb
